Ventilation
We Work with Our Customers on All Aspects of Their Buildings
Ventilation creates a healthier, drier building and helps provide an ideal environment for building occupants and sensitive stored materials. Legacy structures offer fabric building ventilation options to suit your needs.
With Legacy Building Solutions you can rest assured that you are getting a fully engineered building, constructed on time and on budget, with lower building lifecycle costs in the long run.
ventilation of a fabric building
Passive Ventilation
Passive ventilation uses gravity to provide fresh air circulation inside a building with zero ongoing cost and maintenance. Passive ventilation systems may provide enough ventilation on their own, or they may be combined with active systems to provide more air turns. Overhangs, open walls, endwall panels and ridge vents are sources of passive ventilation.
Air intake is best achieved under the fabric structure overhang. This keeps fresh air flowing in at the occupied level of the structure and provides ventilation the entire length of the building. The lighter, cooler air flows in through the overhangs; as the air heats up it rises and is exhausted out the ridge vents.
There are several fabric building ventilation options for passive exhaust systems. An open ridge vent lets warm, humid air push out the peak unrestricted. Or incorporate a one-piece exhaust vent to block rain, snow and birds from entering through the ventilation system. Aluminum ARV vents are a cost-effective, attractive way to provide peak exhaustion.
Endwall panels are another maintenance-free way to ventilate a building. Mesh or aluminum panels are available in any size and several colors to blend in with the building.
Active Ventilation
Fans, louvers and exhaust vents are more “hands-on” ways to create fabric building ventilation. Although these options require more up-front cost and maintenance than a passive ventilation system, they may provide the right amount of air for your application.
Fans and louvers are available in several colors and sizes. Talk to your building consultant for the most accurate information about fabric building ventilation options for your building.

Lyons Salt Company Salt Mine Storage
48,600 sq ft Salt Mining Storage Building | Lyons, Kansas
Lyons Salt Company is a Kansas-based company that mines and produces deicing salt and agricultural feed salt products. Because Kansas law requires salt to be kept under cover, they use flat storage buildings to store equipment and bulk salt. Lyons had a fabric structure on an open web truss system that was severely corroded due to fine dust particles settling on the exposed hollow tube trusses. Lyons specified a fabric structure for the new enclosure – metal buildings corrode too quickly when exposed to massive quantities of salt, and wood buildings are too expensive to be cost effective.

IEI Barge Services is a bulk fertilizer storage, mixing and transloading facility along the banks of the Mississippi River. In 2015, they began shopping for a bulk storage building to accommodate business growth. Poor soil conditions, along with the requirements of loading and storing bulk product and withstanding constant exposure to corrosive fertilizer, made steel buildings impractical and prohibitively expensive. “Because of our soil issues, we simply couldn’t afford to construct a more traditional building,” said Joe Bitter, general manager of Alliant Energy/IEI Barge Services. “The lightweight design of our Legacy building allowed us to reach a compromise between soil conditions and cost.”
